why is the cast of the Scions so...elvish now.

[Raoabolic]

The problem is that you see it from a racial point of view.
Whereas every member of the scions have their places for what they have done in turn since ARR, expansion after expansion.

Why make it a wokism?

Because that's reality. For or against it, this is what the people expect. Just treat it as background noise and pray that if the IP introduces the concepts then it does it in a natural way rather than an obvious shoehorn.
